- Background
- Cyclin T2 is a ubiquitously expressed nuclear protein that is a member of the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns that contribute to the temporal coordination of each mitotic event. This cyclin and its kinase partner CDK9 were found to be subunits of the transcription elongation factor p-TEFb. The p-TEFb complex containing this cyclin was reported to interact with, and act as a negative regulator of human immunodeficiency virus type 1 (HIV-1) Tat protein. Anti-Cyclin T2 Antibody is useful for researchers interested in HIV research, Gene expression, and cell cycle pathways.

- Purification
- This antibody is directed against human Cyclin T2 proteins and was prepared from monospecific antiserum by delipidation and defibrination. Antiserum will specifically react with proteins 74 and 81 kDa in size corresponding to isoforms of Cyclin T2 protein by western blot. A protein:protein BLAST analysis was used to suggest cross-reactivity with Cyclin T2a and T2b from dog (96%), bovine (93%), mouse (88%) and rat (85%) sources based on high homology with the full length protein. Reactivity against homologues from other sources is not known.

- Function
- Regulatory subunit of the cyclin-dependent kinase pair (CDK9/cyclin T) complex, also called positive transcription elongation factor B (P-TEFB), which is proposed to facilitate the transition from abortive to production elongation by phosphorylating the CTD (carboxy-terminal domain) of the large subunit of RNA polymerase II (RNAP II) (PubMed:9499409, PubMed:15563843) . The activity of this complex is regulated by binding with 7SK snRNA (PubMed:11713533) . Plays a role during muscle differentiation; P-TEFB complex interacts with MYOD1; this tripartite complex promotes the transcriptional activity of MYOD1 through its CDK9-mediated phosphorylation and binds the chromatin of promoters and enhancers of muscle-specific genes; this event correlates with hyperphosphorylation of the CTD domain of RNA pol II (By similarity) . In addition, enhances MYOD1-dependent transcription through interaction with PKN1 (PubMed:16331689) . Involded in early embryo development (By similarity) .
